Application filed February 4, 1905. Serial No. 244,161.

To all whom it may concern.-

Be it known that 1, JAMES W. SHONE, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Machines for Manufacturing Building-Blocks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My presentinvention has for its object to provide a machine for manufacturing blocks or stones for building purposes having parts interchangeable with others for making blocks of different sizes and which is also capable of molding blocks or stones having two outer or wall faces arranged at an angle to each other and comprising suitably-arranged parts capable of being readily adjusted to vary the angular relation of said faces.

To these and other ends my invention consists of certain improvements and combinations of parts, all as will be hereinafter more fully explained, the novel features being pointed out in the claims at the end of this specification.

In the drawings, Figure l is a front elevation of a machine constructed in accordance with my invention. Fig. 2 is a rear view thereof. Fig. 3 is a top plan view. Fig. 4 is a bottom plan view. Fig. 5 is a longitudinal cross-sectional view taken on the line 5 5 of Fig. 3. Fig. 6 is a cross-sectional view on the line 6 6 of Fig. 1. Fig. 7 is an end view. Fig. 8 is a View of the mold-box in the open position.

Similar reference-numerals in the several figures indicate similar parts.

In the present illustrations I have shown a machine embodying my invention and comprising a main frame 1, having a longitudinally-extending shaft 2, on which is pivotally mounted a mold-boX-supporting frame. As this is adjustable to accommodate mold-boxes of various sizes, it is composed of two side pieces, each comprising an arm 3, to which is attached the bottom of the mold-box, and a divergent arm 4:, extending at a right angle thereto and supporting one side of the moldbox. The side pieces are secured to the shaft by set-screws 5, and at their upper ends they are connected by a handlebar 6,-by means of which the frame may be rotated from its normal position (shown in Fig. 1) to that shown in Fig. 8 to turn the molded block onto its side before it is removed from the machine.

The mold box is composed of movable pieces or mold-boards, and the bottom 7 thereof is provided near its ends with rearwardlyextending jaws 8, embracing the shaft 2 and secured thereto by cotter-pins 9, any lost motion that may occur being taken up by setscrews 10, which are threaded in the jaws and may be adjusted against the side of the shaft to draw the pins into engagement therewith. The bottom is provided at its ends with flanges 15, which engage corresponding flanges formed on the proximate edges of the arms 3, against which it is held by clamping devices comprising handles 16, pivoted on pins 17 and rotating in the plane of the arms to carry their inner ends 18 laterally into and out of operative position beneath the ends of the bottom. Provided on the inner end of each of the handles are wear-pieces, such as screws 19, which may be adjusted so that the bottom 7 may always be clamped firmly in position. When it is unclamped by turning the handles on their pivots, the bottom may be rotated outwardly into engagement with depending stops 20 on the arms 3, as will be further explained.

The front side of the moldboX (indicated by 21) is pivoted to the edge of the bottom at 22 and extends upwardly, as shown in Figs. 6 and 7, to cooperate with the end boards 23, with which it is locked in engagement by handles 24, pivoted on said boards and provided with offsets or shoulders extending over the ends of the side 21, through which project set-screws 25, cooperating with curved eccentric surfaces of bosses 26 thereon. The rear side of the mold, formed by a removable pallet-board 27, is located between the ends 23 and rests upon the bottom. 7 being held in place by inwardly-extending flanges 28 on the proximate sides of the arms 4. Also provided on said arms are ribs 29, which extend outwardly, as shown in Fig. 3, to form a guide for the hinge members 30, to which the doors 23 are detachably secured by the pintles 35. Each of the hinge members has an end 36 extending in rear of the flange 28 and provided with a set-screw 37, the end of which projects into a longitudinally-extending recess 38, formed of sufficient depth to permit the screw to be loosened and the member adjusted longitudinally on the arm without its being accidentally disengaged therefrom.

The parts heretofore described are those employed when the usual rectangular blocks are molded, and if it is desired to make these hollow in form a core 39 may be used, which is inserted through an aperture in the front board 21 and temporarily secured by a pivoted cross-bar 40. Blocks of various sizes may be molded by substituting mold-boards of different length or width, and to further adapt the machine for forming blocks having two wall-faces, which are disposed at other than a right angle or which have one face extending at an angle toboth the longitudinal and the transverse walls of the block, I provide additional parts, as will hereinafterappear.

Informing a block of this character the front and'rear side, pieces or mold-boards 21 and 27 are formed of greater width at one end than at the other, as indicated by 45, and one of the end pieces 23 'is' preferably made of corresponding height. The bottom piece employed is provided with a transversely-extending groove orrecess 46, in which engages the end of an auxiliary face-plate 47, having at its outer end an extension 48, forming an end for molding the'end face of the block. In order that the extension or plate 48 may be readily removed, it is detachably connected to the plate 47 by book connections, which are adapted to normally support the plate 48 in the desired angular position on the plate 47, but permitting it to ,be. rotated outwardly thereon away from the block.- In the present instance these connections are formed by providing the face-plate with an offset 49, at its outer end forming an open channel beneath the overhanging end 50 thereon, and the plate 48 is provided with acorresponding offset end 51, adapted to fit the recess or channel and to engage beneath the end 50. The end plate 48 is further supported by means of a pin or stud 52 projecting through an elongated aperture 53, formed in the front board, 21 of the mold-box upon an arc described from the lower end of the face-plate 47, whereby an adjustment of the pin in the slot will cause the face-plate to be adjusted to vary its 'angularity. The pin 52, projecting in rear of the end plate 48, is sufficient to support the parts, but as both the end plate and the face-plate are subjected to strain and the jarring action caused by packing the material in the mold the former is provided with a shoulder 54, engaging the pin, and an additional adjustable support is provided for the face-plate 47. In' the present instance this support comprises the plate 55, supported on hook-shaped fingers 56 at the lower edge of thedoor 23 and extending between theinner faces of the side boards 21 and 27, where it engages the end of the plate 47 at such an angle that the plate is supported across its enrest on the pallet.

'tire width, and its lower end is forced downwardly into close engagement with the forward edge of the recess 46, preventing its disengagement therefrom. The plate 55 is held in adjusted position by means of a setscrew 57 and it is further locked by a similar screw 5.8, bearing against a rearwardlyextending projection 59 on the plate. When blocks having angular wall-faces are molded, it is also desirable to provide the angularlyextending portion of the block with an aperture, and to this end a supplemental core 60 may be employed similar to the core 39, which is centered by passing it through an aperture in the front board 21, where it is secured by a pivoted strap 61.

The operation of the machine will readily be understood from the foregoing description and the accompanying illustrations. When it is desired to mold a building-block of the usual rectangular form, a mold-box of the desired size and pattern is selected, and the parts thereof are secured to the supportingframe, the side pieces of which are given the required adjustment on the shaft 2. The mold-box is then closed by securing the bottom 7 to the arms 3 by means of the clamping devices 16, when the front and ends are closed and secured by the locking devices or handles 24. The molding operation may then be performed in the usual manner and the box tilted or rotated to turn the block on its side face, when the bottom, front side, and ends of the box may be opened, as illustrated in Fig. 8, permitting the block to be removed on the pallet 27. The same operation takes place when it is desired to mold blocks having the angular wall-faces, the only changes necessary being the substitution of the speciallyformed parts of the mold-box, which are secured in operative position, as before described, and the face and end plates 47 and 48 inserted, as shown in Fig. 5, and secured in the desired position by the adjustment of the pin 52 and the plate 55. As the only connection between the sides of the mold-box and the inclosed face and end plates is the pin 52, it will be seen that after the block has been tilted onto its side face and the side 21, together with the bottom 7, is rotated out of engagement with the block the face-plate and end plate will be disengaged and allowed to The end plate may then be rotated away from the end of the block and its book connection with the face-plate disengaged, permitting the latter to be also removed vvithout marring the face of the block.
